Christian Mentzing Personal Training

Fantastic experience: As someone who trains seriously in CrossFit and other sports, I’ve worked with a few different nutritionists before. But every time, I hit a wall — especially when it came to building strength and muscle without losing performance. Whenever I gained strength and muscle, I also gained too much fat and felt slower in gymnastics. When I lost weight, my gymnastics performance went up, but I became noticeably weaker in lifting. I could never find the right balance… until I met Christian. From the very beginning, he took a completely different approach. Instead of trying to make me gain weight, he first focused on helping me lose fat and balance my hormones. Honestly, at first I was a bit skeptical — I thought, “Wait, is this the right direction?” But he explained everything clearly, especially how fat loss, insulin resistance, and hormonal balance are deeply connected. As a chemical engineer by background, his reasoning made total sense to me. In about three months, we lost around 5 kg of fat in a very balanced way — almost all from fat, very little from muscle. My hunger levels stabilized, my energy improved, and my gymnastics performance increased noticeably. After that phase, we gradually moved into strength and muscle gain. Now, I’m in the muscle-building stage — and for the first time, I’m gaining muscle and strength without increasing my body fat. It’s a very well-structured and professional process. Christian doesn’t just design meal plans; he builds a strategy around your goals, metabolism, and hormonal balance. Whether your aim is fat loss, muscle gain, or athletic performance, he truly knows how to create a personalized, sustainable plan. Highly recommended

Fantastic experience: Christian it was the best personal trainer I never met before ! He is really professional , attentive , is not just a “ challenge “ for the client but it also a challenge for him , to make sure what you asked at the beginning of this path you achieve . He always gave me support also on when during the path the road is not always straight , but up and down . I choose a plan with the nutrition and he made the perfect Mediterranean diet , this is actually what my diet was obviously he made everything with a professionalism . I’m happy to watch me at the mirror and see what I achieve , thanks to me but a massive thank to him to gave me the perfect workouts, diet , support , discipline and making sure don’t do the same mistakes I did in the past to make sure to maintain the weight throughout the years ! Thank you Christian for all this !

Fantastic experience: From day one, Christian took the time to understand my goals, challenges, and lifestyle, creating a dynamic program that’s not only effective but genuinely enjoyable. Each workout is thoughtfully planned and tailored to my progress. He knows how to push me in the best way possible—encouraging, supportive, and always keeping things fresh and challenging. I can’t recommend him enough

Fantastic experience: I was an online client of Christian, who not only completely transformed my life but made the process highly enjoyable too. His plan fit into my very busy life perfectly, his support was relentless and he was always available. Previously when I had PTs in person, my results were lackluster and I always though I was at fault for not working hard enough. Turns out, all I needed was a plan that worked and a coach that cared, and I found that in Christian. Highly recommend.

Fantastic experience: Amazing results with Christian

Fantastic experience: He is an amazing coach. He doesn't just focus on training; he also tries to understand my motivations to help me train better. A 10 out of 10.

Fantastic experience: I started training with Christian just over 3 months ago. He is truly excellent! The rigour and focus he places on both workouts and diet is exemplary. From the first day, I felt I received world class training techniques, coupled with a real focus on the food/nutrition - he asked me to take photos of everything I ate! The app Christian uses makes tracking everything very easy to follow. Highly recommend him to anyone looking to make a real step change in their fitness routine!

Fantastic experience: After many years of not taking good care of my health, I decided it was time to go back to the gym; however, this time I had to hire a professional to guide me through the workout. Not only did Christian help me with the lifestyle changes I had to make (diet, better sleep, etc.), but he was an incredible motivator. The exercises were tailor-made for me, and after 2 months following his program, I could already see the changes in my body. Not to mention, the energy levels are so much higher, and the pain I had in my body (due to years of sitting in front of the computer for work) was gone. Overall, my life is happier because I am healthier, and I only have Christian to thank for it. I cannot recommend his services enough.

Fantastic experience: I started training with Christian back in 2018, he helped me get back in shape after my back injury. He's an exceptional and dedicated trainer, who really cares about the overall health and wellbeing of his clients. His programs are challenging (deep down they really are fun) and well rounded, making sure I get the most out of each gym session. He is also a strong advocate for a healthy and realistic lifestyle. He also makes sure I stay on top of my nutrition. I'm so happy and grateful to have him as my trainer and I look forward to further achieving my fitness goals with him.

Fantastic experience: Christian has been an excellent PT/Nutrition/Lifestyle coach. Since beginning with him 9 months ago, I am 15kg down, less injured through my training than I was previously and my body shape and approach to food, exercise and drink has completely transformed. Most importantly, I am feeling the healthiest and strongest I've ever felt. Thanks Chris!

Fantastic experience: It was amazing having Christian as a trainer, he is dedicated, empathetic and results driven. During my training sessions with him I learnt so much, not only about weight training but also about nutrition. If you’re looking for a personal trainer who really cares about both physical health and wellbeing, I would highly recommend Christian.

Fantastic experience: Fantastic coach, couldn’t fault a single thing. Christian is excellent in all aspects of coaching the knowledge he has is remarkable he’s is tough but fair and you will reach your goals if you follow his instructions without a doubt.

Fantastic experience: I started working with Christian in June 2023. Since then, I improved my understanding and relationship with food and train regularly, things that seemed impossible at the time I started. Of course my physique has changed a lot for the better but what is amazing is how I feel: more confident. He is an amazing personal trainer, he takes a lot of time and has patience to explain and answer any questions you might have. He is friendly but also knows how to motivate you and put you back on track. I worked with other personal trainers and I can say that with Christian the communication and understanding makes the difference for long lasting benefits.

Fantastic experience: From not even considering going to the gym, to integrating the gym into the routine. I couldn’t believe it. You thought me to be patient and the changes must be for lifetime. It was not only a physical change, but a mental one. Working with you, I learned how much sport helps in the most stressful times and not to beat myself up even if it doesn't turn out the way I want. You are definitely

Fantastic experience: Chris has been brilliant in working with my specific needs and truly understands what is necessary to help me meet my goals. His detailed approach to nutrition and fitness plans has exceeded my expectations. He is always at hand when needed, responds to messages quickly and is really good in making you feel motivated. The difference in having a coach is massive, highly recommended.

Fantastic experience: I’ve been training alone for 10 years and constantly for 2. I did everything in my opinion: regular training, eating quite healthy and staying as active as I could. Still, something was missing, as I couldn’t see any changes in my physical appearance. Three months ago, I got in touch with Christian, and since then, my life has changed! In less than 3 months, he managed to change my body more than I did in 10 years. He is an incredible person, always there to support you, amazingly knowledgeable and encouraging! He has an outstanding patience and empowers you to believe in yourself, which is such a unique quality! He changed the way I looked at training, my relationship with food and my habits. He hasn’t just helped me get into shape, but thanks to him, I can say I am a much better person, much more balanced, my confidence has boosted and all the pillars of my lifestyle have fallen into place, like perfect puzzle pieces. It’s not only about how well my body looks now, but it is about feeling stronger than ever, healthy and ready to treat anything life brings to me just like my training: step by step, with confidence and perseverance. Thank you Christian for everything you teach me and for showing me what I am really capable of!

Thank you Christian

Fantastic experience: Have been trainings with Chris for a year now! The experience with Chris was absolutely a gentle breeze. One of the top level PEs in this country I’ve ever dealt with. Very professional, patient, honesty and helpful!

Fantastic experience: The reason I give 5 stars is because there is no 6 starts available couldn’t be happier about Christian. He has knowledge and also very thoughtful and kind.

Fantastic experience: I had lost almost 9kg in 12 weeks and I never had to starve myself! I gained so much self confidence and discipline with the support and coaching from Christian Mentzing. I highly recommend Chris if you’ve been struggling to lose weight for a couple of years and you’re fed up of trying again and again with no sustainable results. Chris isn’t one of those rude Personal Trainers who tries to push you for more sessions for their own financial gain. He really cares about the wellbeing and fitness of his clients. Even on my bad days when I felt low; he was understanding, taught me balance, self control and not to be hard on myself. Now I feel more confident in the gym and making better food choices without having to completely cut out foods that aren’t the best to have on a regular basis. The weekly reviews from himself were very helpful as well as I could comprehend the importance of being consistent even though I was not always perfect with the customised plan. This fitness online coaching with Chris has been best investment for myself in 2023. I can finally take a full length picture of myself and not hate it (self-love).

Fantastic experience: Super nice trainer and really excellent at getting you on the training patch. Really recommended

Fantastic experience: I trained with Christian from 2017 to 2018 and achieved rather amazing results. I dropped 19kgs in 16 weeks and Christian will tell you it was all my hard work. But in all honesty if I didn’t have him pushing, coaxing and from time to time some straight talking, I’m not sure the results would have been so amazing. The attention to detail from the gym floor work out, meal coaching and planning advice, the morning emails asking for meal plan, weigh in and goal setting all kept me accountable and on track. Not only did I gain a physique I hadn’t had since my 20s, I was 47 when I started with Christian, I learned how to maintain, train clever and not waste time in the gym on my own. I have recommended Christian to many people and all have been impressed by his unique way of getting the best out of people, even myself the most reluctant gym bunny became a weight training devotee. If you are looking for a trainer who knows his stuff, can keep you on the straight and narrow and get results that you just didn’t think could be possible. If all you want is someone to count reps any mediocre PT can do that, but if you’re keen to learn, develop and be pushed get in touch with Christian he’ll have you deadlifting before you know it and with a transformation you never thought possible.

Fantastic experience: I decided to get a trainer after training alone for about 6 years and I have been training with C for almost a year. My body has completely changed since we started and I‘m much better informed about how to properly train and the precision of my nutrition. Within a short amount of time he changed my approach to training and the gym has never been the same since. This is the guy you want if you‘re looking for a smooth transformation.

Fantastic experience: I loved the training experience I had with Christian. Everything he made me do was efficient and I got amazing results. It was not all about training as, he basically provided everything I needed and the support he gave with is amazing personality makes the experience even better! Thank you Christian for being the step for getting me where I was before as physically

Fantastic experience: I lost 9kg, got lean and build real muscle. I was shocked on what’s possible when you get a trainer who really tailors the work out to your goals and needs! Everyone is different and everyone needs personal care. That’s what you get with Christian. Nothing but care and results.
